# Crossref Citation

> Use this tool when you need to resolve academic paper citations and retrieve formatted bibliographic data. It solves problems of inconsistent citation formatting and inaccessible metadata by parsing various input types, including DOIs, arXiv IDs, and PMIDs, and outputting in multiple formats such as CSL-JSON, BibTeX, and RIS. It is ideal for use cases requiring reliable and efficient citation retrieval, such as academic research, publishing, and reference management.
